Housing all components (except for absolute encoder and inspection travel device) in the rear box of a tablet instead of the panel described above is the minimum solution of the KS.
Without compromising functionality, a tablet with the dimensions 132 x 1500 x 75 mm (60 mm behind the car wall and 15 mm protruding) can be used. A cutout of only 129 x 1440 mm in the car wall is required into which the tableau is inserted.
